Chiller sizing problem

[terryansimon]

chilling water can get better? than whats the non-better type of chilling?

if ur tank size is big of course big chiller

small tank small chiller doh ~ no need to calculate till so chiem

the reason why we calculate until so cheem, is to make sure we know where our money is going and to make sure we are spending our money wisely.

impulse buying, in this hobby or anywhere else for that matter, can and will lead you into serious debt trouble, both short term and long term.

hence, people like to talk about the potential pitfalls of investing in a chiller that is bigger/smaller. ultimately, everybody is paranoid about the amount of dough coming out from the wallet as a result. face it, you'd be worried too if you were in the same predicament. (=

Like you, never believe in chiller before.... kena a lot shit, bang a lot of wall, do a lot of studies..... put a chiller in -> less problem.

Why go into such length calculating? U will if you are the one paying the bills.

point to add ...

>JBJ arctica 1/3hp titanium chiller . Refigerant R-134A

DBM-250 capacity 1,000w, volts 230v, amps 3.5

thus watt consumption is 3.5a x 230v = 805w!!!!

(watt consumption from > http://www.eaquanature.com/store/product_i...products_id=782 is 565w only !!! ???? but with 3.5a , the watt consumption is 805w )

>commerical series JBJ arctica 0.5hp. Refigerant R-22

DA-500B capacity 1170w, volts 230v, amps 2.8a

thus watt consumption is 2.8a x 230v = 644w!!!!

Hi piglet!

I think the mistake u made here is multiplying the 230v. I think the 230v refers to the AC power supply. Anyway, one should judge the power consumption by the hp and the efficiency by the cooling rating it states (if any) with similar hp chiller.

Hi sis..

Yup. 230v refers to ac power supply. impossible>>230 direct current.

all the above infor/specification >taken from jbj brochure from (Aqua-nautic specialist ltd) local dealer.

The amps stated in the brochure > should be operating amps.

thus 0.5hp DA-500B~ 2.8x230v = 644w.

0.3DBM=250~3.5x230v = 805w.

Main reason for the difference in watt consumption >

1/3hp is using r-134a refrigerant and 0.5 commercial unit use R-22 refrigerant. Thus in order to run r-134a ,1/3hp run on compressor that consume higher watt than 0.5hp commerical unit.

Also> commerical series use titanium 'helix' coils that offers better heat exchange than residential' series etc.

The cal' watt should be close to actual watt consumption. unless the amps stated in the brochure > not operating' amps. just want to share and discuss with reefers here. hopes that 1/3hp really consume 565w only and not 804w!! .. esp i am going to use 1/3hp too - don't want to see piping in my hall ..so can't use 0.5hp
